The UCL - Ultimate Chemical Light - Desk decoration

thingiverse

Here is my recently ended project: The UCL (Ultimate Chemical Light)! Even if there isn't any chemical reaction in this object, I used old reformed tubes (diam 22mm) and found a way to use them in the cooler way as possible. The 4 tubes are lighted by 4 leds, just right positionned to diffuse the light in the containt of the tubes, and color changing! I designed the Ucl_body in Solidworks, and printed it. I used 4 rgb leds like these : https://www.amazon.fr/gp/product/B011BGA7VI/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 An arduino pro mini like this one: https://www.aliexpress.com/item/1pcs-lot-Pro-Mini-Module-Atmega328-5V-16M-with-Arduino-Compatible-With-Nano/32672852945.html?spm=a2g0s.9042311.0.0.283c4c4dJrcD2q And a switch, and also a FTDI module to upload the sketch in the arduino. The pro mini has only 6 PWM ports, so like I had 3*4 pins to command, I simply welded 1 color of 2 leds on the same pin^^ And it works great! Also surelly possible with Neopixel LEDs or another controller. The arduino code is in the files. Good luck dear Maker! ^^
